The .advantagespresented by the use of tippingcontainers'iiiounted on the chassis of motor-lorries, as i'egards loading and unloading all kinds yof material, are well- 5 known. l

This invention 'consists in certain arrangements of the lifting lcables which prevent any warping of the tipping receptacle, in case of irregular loading of this latter, and ensure progressive speed in the raising operation.

A form of realization of the invention is shown diagrammatically and merely by way of example in the accompanying drawings, wherein: i .l Figure 1 is a side elevation of a tipping receptacle provided with an arrangement of lifting ropes constructedy according to the present invention; and l Figure 2 is an end View of a tipping receptacle provided with a system of ropes according to the present invention, the guiding pulleys lof each pair being spaced apart relative to each other for the sake .of clearness.

In the example shown, the receptacle l1 is pivoted at 2 upon the chassis 3 and a standard 7 is mounted at the front Vof this chassis,

in which standard a tube-11 can telescope 30 under the action of a worm 8 driven by pinionsl 9 and 15 which are rotated either by the engine of the vehicle, or by means of a crank. At the extremity of the telescoping tube 11 a cross-piece 12 which carries at its extremities guiding'pulleys 72, 7 2 and 7 3, 73,

is rigidly mounted. Y y

The standard 7 could be mounted obliquely upon the chassis 3 of the vehicle, or as shown in the drawing, could be arranged so as to pivot during the tipping movement of the receptacle about a shaft 6 rotatingin a casing 5.

The lifting movement of the receptacle 1 is leffected according to the'present invention, by means of two cables l and 4L which are attached at 71 and 71 to the front of the receptacle and pass respectively over pulleys 72 and 73, 72 and 7 3', mounted at the two extremities of the cross piece 12 and are then attached at 74 and 74 to the chassis `of the lorry.

The pulleys 72 and 72 are independent and are preferably loose on the same axis,

, and the same is the case as regards the pulleys 73 and 73. v

supposing, for example, that the recep- Itacle1carries-at71 aflojad ,of 3000 kilos .and

at 71"'aloadofQGOOtkilosfthe difference of l the load will ynormally tendl to distort the receptacle when it rises or to deform the arms of the cross piece 12. But, thanks to the arrangement, on both sides of the raising mechanism 7, of the points of attachment 71 and 74, and 71 and 74 of the cables 4' i and 4L respectively and the mounting .of the pulleys 72, 72 and 73, 73 at the extremities of the twoy arms of the cross piece 12, the stress to which the pulley 72 is subjected iS transmitted to73 and the stress supported by thepulley 7 3 is transmitted to the pulley 72," and the result is that thel different stresses exerted upon the two arms of the cross piece 12 balance eachother and consequently stop any oscillation or deformation, either yof the cross piece 0r -of the receptacle. Having thus described my invention what I claim and desire to secure by LettersPatent of the United States, is:

l. A tip wagon comprising a i chassis, a i truck body pivoted on the chassis, a hoisting f mechanism for the truck body including Aa movable cross arm, a pair of pulleys mounted infeach end of said cross arm, a cable having one end connected to the truck body at one :side and extending upwardly and over one of the pair of pulleys at one side of the cross arm, thence extending along the cross arm to one of the pulleys at the oppo- 'site side of the cross arm, and thence downwardly to the opposite side of the chassis-to which same is affixed, a second cable attached at one end to the truck body at the side opposite to which the rst cable is attached, said cable extending upwardly and over the other pulley of t-lie pair at the second named side of the cross arm, thence along the cross arm to the other pulley of the pair at the first named end-of the cross arm and downwardly to the chassis to which the other end of this f second cable is aixed. t l 2. A tip wagon .comprising a chassis, a pivoted dump body on said chassis, a. hoisting mechanism for the dump bodyl including a transverse vertically movable cross arm, i

shaftsat opposite ends of said cross arm, pairs of pulleys mounted upon saidk shafts, and a ypair of cables attached to the chassis and dump body and extending over said pulleys, one of said cables being attached to the i i lio at its other end to the left side ofthe chasy right side of the dump body` at one end and sis, the intermediate portion of said cable' being brought up from its `attachifnent to the body over one of the pulleys at the right side of the cross arm, thence along the cross arm and over one of the pair of pulleys at the opposite end of the cross arm, and thence downwardly to the point of connection lat the left side of the chassis, the other cable being affixed at one lend to the left side of the body and at its opposite endto the right side 1U of the chassis, the intermediate portion o vend of said cross arm, thence along the cross arin to the other pulley at the right end of the cross arm, and thence downwardly to the point of connection at the right side of the chassis.
